The OP is correct, there were no Sekine Medalist models. That was a name started by one of the forum members who little about the Sekine models. In fact why he chose "Medalist", when the head badge sates "Medialle" is beyond me. It doesn't even translate to "medalist", though the Japanese may have made some transcription error, inadvertently changing the meaning.
Regardless, the subject bicycle is beautiful example of a Sekine RM-10, circa 1979-1980. It is not a racing bicycle but what used to be called a recreational/touring bicycle. That is not to imply a "grand" touring bicycle. It doesn't have the amenities for multi-day touring with a heavy load. It was designed more for an avid cyclist for who had no aspirations to compete but enjoyed, longer day rides.
The combination of Tange Champion #2 and Shimano 600EX makes it a solid mid-range model for its era. Original pricing was around $300 CDN. It might not be collectible in the USA but these have a good size following in Canada. I'd say the pricing was fair and if you're in a larger metropolitan area, such as Vancouver, it would be considered a bargain.
